A new class of liquid crystal elastomer (LCE) incorporating polyrotaxane-based slidable cross-linkers (PR-LCE) was synthesized for the first time. In particular, we focused on the damping performance of the PR-LCEs using dynamic- and mechanical-energy dissipation method. Interestingly, both the soft elasticity and mechanical damping of the PR-LCE were considerably enhanced compared to conventional LCEs. In addition, it was revealed that the number of cyclodextrin (CD) rings could be an interesting molecular handle to further tailor the damping properties of PR-LCEs. The unique energy dissipation behavior of LCE with slidable cross-links can be useful for developing high-performance sound/vibration dampers and protecting apparatus.
